They are "casting" holes left from the manufacturing process. The source of water would have to be either from the overflow entrance, a crack or pin-hole in the sink basin, or a faulty or improperly installed p.o. ( vertical drain pipe from lav to p-trap).

Using a sump pump basin with holes for drainage in a basement helps to prevent water buildup, reduces the risk of flooding, and improves overall basement moisture control. The holes allow water to enter the basin, which is then pumped out by the sump pump, keeping the basement dry and free from water damage.
The sink sits on the pedestal and there is a hole or slot on the bottom edge that rests against the wall. A large screw or lag screw is put through these holes and into the wall. There should be a 2x6 or wider board in the wall for this purpose in the original construction.
There is a drain at the bottom so the basin can be emptied, and there is an opening (another drain) near the top so that if someone leaves the water running, the water will never reach the top of the basin and overflow.

Having holes in a sump pump basin can lead to water leakage, which can cause flooding in the basement or lower levels of a building. This can result in property damage, mold growth, and potential health hazards. It is important to ensure that the sump pump basin is properly sealed to prevent these risks and consequences.
The little holes on the underside of a leaf are called stomata. Stomata are responsible for gas exchange in plants, allowing them to take in carbon dioxide for photosynthesis and release oxygen and water vapor. They also help regulate the plant's water balance by controlling the amount of water vapor that exits the leaf.
They breathe through the stomata and other pigments.Plants have these tiny holes on the underside of the leaves that allows them to absorb co2 and produce O
it could be coming from a valve cover gasket that is leaking
Young children are easily curious individuals and as such, will explore the world they are in. Pedestal fans, while convenient, are dangerous due to the open holes which children may put their hands in injuring themselves. In addition the rotating portion of the fan is an easy trap for curious fingers. The wires of these fans may also fray posing an electrical danger.
door drain holes are plugged. open door and look at underside for drain holes. open them with a small screwdriver. door may need vacuuming inside to remove crap like pine needles that get inside.
Spiders breathe in oxygen like humans do. They have small breathing holes called spiracles located on the underside of their abdomen that allow them to take in oxygen from the air.
